Back in the day, dashboard elements such as a speedometer, tachometer, and fuel gauge felt like an absolute novelty. Today\u2019s car buyers are far harder to impress. Touchscreen displays, real-time in-car navigation, a variety of infotainment options, and even business tools are what drivers have come to expect from premium vehicles and more budget-friendly alternatives alike.<\/p>\n

In the nearest future, the automotive industry will add more than 44 million new display systems, enabling all-new content flexibility for automakers to attract new consumers.<\/p>\n\t\t\t\t<\/div>\n\t\t\t\t

Vehicle connectivity is now a given. Over 60%<\/a> of US drivers and 24% of EU drivers<\/a> used connected vehicles in 2021. By 2025, the numbers are expected to increase to 70% and 49%, respectively.<\/p>\n

Built-in sensors, local wireless networks, and SIM network connectivity, coupled with software-defined architectures, have enabled an unprecedented level of in-car innovation. Nearly every OEM now has a vision for a fully computerized car.<\/p>\n

Mercedes-Benz<\/a> plans to offer \u201csupercomputer-like performance\u201d in every car with automated driving sensors and advanced navigation technology. GM plans to unveil an end-to-end software platform, Ultifi<\/a>, in 2023, which will enable new in-car subscription services and over-the-air (OTA) software updates.<\/p>\n

Stellantis has an ambitious Dare Forward 2030<\/a> strategic plan, calling for major digitization across the brand portfolio and the launch of a unified software platform, which has a target of \u20ac20 billion<\/a> in incremental software-enabled revenue.<\/p>\n

Less than a decade ago, only premium vehicles contained 100 electronic control units (ECUs) and 100 million lines of code<\/a>. Today, every low-end vehicle hosts an equivalent number of technologies, as Advanced Driver Assistance Systems (ADAS) have become standard.<\/p>\n

To further capitalize on car computerization, however, OEMs will need to get two components right \u2014 backend system implementation and human machine interface (HMI) design.<\/p>\n

HMI design is key to selling the connected car experience<\/h2>\n

A car HMI is made up of functional elements (such as the vehicle dashboard, head-up display (HUD), and instrument cluster), as well as different interaction modalities (touch, voice, haptic, eye movement) that enable effective driver experiences.<\/p>\n

In the best-case scenario, poor interactivity upsets the user; in the worst-case scenario, it can create dangerous on-road situations.<\/p>\n

That\u2019s why a third of an ECU\u2019s software<\/a> is now dedicated to ensuring quality vehicle performance and powers safety-critical systems such as emergency braking, airbag deployment, traction control, and collision warning.<\/p>\n

Effective HMI design helps users drive safer by progressively discovering new in-car features. Users\u2019 feedback must be effectively captured and communicated back to the machine, which, in turn, must adapt its performance.<\/p>\n

As one of the ten usability heuristics for UI design<\/a> suggests: \u201cThe design should always keep users informed about what is going on, through appropriate feedback within a reasonable amount of time.\u201d<\/em><\/p>\n

HMI shouldn\u2019t add extra complexity. On the contrary, it should make the user experience more intuitive.<\/p>\n

Because here\u2019s the deal: Users don\u2019t always understand the perks of car connectivity<\/a>.<\/p>\n

An FIA survey<\/a> found that in France, 70% of respondents claimed to have knowledge about connected cars, but only 59% could accurately define what they are.<\/p>\n

Likewise, not all consumers are eager to share data about their driving behavior or preferences in return for access to services. This indicates a gap in understanding how in-vehicle connectivity generates extra value and how automakers will guarantee the privacy of users data.<\/p>\n

The challenge of great HMI design is to progressively introduce consumers to the value of new connected services and features until they have an aha! moment \u2014 a breakthrough realization of the beauty, efficiency, and attractiveness of the HMI solution.<\/p>\n

Drivers aren\u2019t always ready to pay more for OTA maintenance updates, but they sure want to shell out extra for greater vehicle safety<\/em> and reliability<\/em>. Likewise, HD maps may sound less attractive than the promise of higher fuel\/energy efficiency<\/em>.<\/p>\n

HMI design helps connect the dots between new in-car features and real-world benefits customers are seeking.<\/p>\n
